Depending on the amount withdrawn and the account used, there are a number of options available to you:
- if you are on good terms with your partner, you may wish to begin by asking them to provide an explanation for their actions. You might be able to agree that the funds ought to be returned and otherwise reach agreement on how to conduct the account in the future. Alternatively, a lawyer could write to your partner and/or their lawyer on your behalf;
- you could contact your bank or financial institution and enquire about closing the account and/or requiring joint signatures for any transactions;
- you can also seek an injunction from the Court to prevent your partner from withdrawing further funds from the account.
